PENNSYLVANIA, ASSIGNQR TO ISRAEL WARD AND JAS. TEMPLE.

= MACHINE FOR BoRING FENCE-POSTS.

A Specification of Letters Patent No. 12,808, dated May 1, 1855.

\ Beitknownthat I,JAMEs` TEMP'LE,of Birmingham, in the `county of Huntingdon and State of Pennsylvania, have invented certain new and useful Improvements` in Machines for Boring Holes in Fence-Posts; and I do herebydeclare the followingto be a full, clear,a`nd exactdescriptionY of 'the same, reference beinghadtomthe accomi panying drawings, making a part thereof,

Figure l, representsa top view, andFig. 2, represents a view from oneoif the sides.`

Similarletters in fboth the iigures denote like parts.

`The nature of my 'invention consists, in

`1 hanging the longpinionwhich giveslmotion j j `to the angers through `the spur wheelson 1 their shanks,an`d the'shanks of theaugers,

' in adjustable holsters or pillar blocks,` so

that the angers may `be .set farther apart, `or nearer together, to bore the holes at variable distances,twithout allowing their spur wheels `to be out of t gear with saidylong and `use my invention, Iwill proceed to describe the same "with'reference to the drawings.` i i A, A, A, is a horizontal frame supported upon legs B, B, and on said Viframe is a sliding carriage C, upon whichu the main part of the machine is supported. `The middle longitudinal piece of theframe is pierced i with holes a, a, in any` suitable number, and at distances apart to `correspond with the usual distance between the ordinary post holes, anda pin b, passing through the car- I,riage C, .holds said carriage at the point desiredfto work theiaugersQ` The post to be "bored is held against the standards D, by

the screw rods x t Upon the carriage C, `are arranged three bolsters or pillar blocksiF, F, F. These i. t pillar `blocks have a rule `joint at their apex (as u seen in` Fig.` 2,` more particularly) and their bases where theyrest on the carriage ,y eC, are `slotted asseen at c. A set screw Gr passes through the carriage and through theseslots, so that thebolsters may bespread Y `at the bottom and consequently be lowered `in\height,jand` when adjusted at the proper "height, are made fast by the set screws.

l H, is a long pinion provided with suitable cogs or teeth, and its journals or shaft have their bearings in the bolsters F, F. On the outside journal lof thelong pinion, is arranged a balance wheel I, having a handle J in it, which serves the purpose of crank and balance Wheel. i j

` In the bo-lsters F, F, are supported the auger Shanks K, K, each of themhaving on l their inner ends, spur wheels L, L, which mash with andreceive their motionfrom the long pinion H. As the bolsters are lowered by spreading out their bases, the spur gears roll around the periphery of the long pinion which lowers with the bolster-s, but still remain in gear with said pinion, the

distance between their respective journals and the journal of long pinion not changing. But as the holsters areI lowered the spur gearsspread out, and thus spread farther from each other the angers. By raising the bolsters, the reverse adjustment is had, andV thusk mortises ofany desired length,or at any suitable distance apart may be bored on the same machine.` i

M is a lever, pivoted at d, at about its center and connected at its extreme end to a crosshead N which is restrained by collars e e, on the shanks of the angers. When the po-st is clamped and motion given to the machine, `the operator takes hold of the lever M, and forces up the angers into the post, the spur wheels on their Shanks sliding onthe `long pinion, but at the same time they are rotated by it. have ybored through the post, t-he motion of the lever is reversed and they are runA back for the neXt operation, after the car- `riage has been shifted to the neXt set of holes to be bored.

When the angers j Having thus Vfully described the nature of my invention what I claim therein as new and desire to secure by Letters Patent, is-

The supporting of the long pinion and the auger shanks in the adjustable hinged pillar blocks, such as described,I so that the` angers may be set to bore holes at variable distances apart, whilst the spur wheels on their shanks shall still keep in gear with the long pinion as described. hi
